Adapting and Validating the Indonesian Version of the Masturbatory Premature Ejaculation Diagnostic Tool: A...

Objectively diagnosing premature ejaculation remains a challenge as it has traditionally been defined only through diagnostic criteria based on vaginal-penetrative activity. However, male sexual activity is diverse, ranging from penile-vaginal intercourse to solitary practices such as masturbation. Masturbation is highly prevalent in the general population, particularly among younger men who often report premature ejaculation. This presents a specific challenge in diagnosing premature ejaculation in men who do not engage in vaginal-penile intercourse and rely solely on solitary sexual activity, such as masturbation. Therefore, we translated and psychometrically validated the Indonesian version of the Masturbatory Premature Ejaculation Diagnostic Tool (MPEDT) in Bahasa Indonesia to facilitate and expand the application of sexual assessment in sexual healthcare, thereby enabling more comprehensive management of premature ejaculation. The Indonesian version demonstrated good construct validity, internal consistency (Cronbach's α = 0.88), and good temporal stability and reliability (intraclass correlation coefficient = 0.76), supporting its potential use as a screening instrument for masturbation-related ejaculatory symptoms in clinical and research settings. Furthermore, based on our analysis, an MPEDT cut-off score of ≥ 9 may help identify individuals who may benefit from further clinical evaluation.
